Element barline is used for the description of different kinds of barline. Repeated barlines should not be encoded using this element.

Attributes

style, an attribute to specify the graphical aspect of the bar line.

extension, an attribute that encodes the number of staves the bar line is applied to: single_staff for the staff of the current event only, staff_group for the group the current event belongs to, all_staves for the whole staff system, and mensurstrich for lines only between pentagrams.

event_ref, a mandatory attribute to identify the spine event that precedes the barline to be specified. If a single staff is involved (see attribute extension), the event identifies the staff to modify. Please note that events are associated to parts, that are associated to staves. If a group is involved, the group is the one containing the staff of this spine event.
